Help!! Wiring 2-12 CVX 2 ohm to kicker zx1000.1!!!

[wptightend 10+ year member]

Okay guys I need a little help im on my own here. I have helped on a few installs etc but I did this one solo!! I have 2 12 inch kicker cvx dual voice coil subs they are 2 ohm. I have a zx1000.1 pushing them. I wired them with 1/0 rockford fosgate wire. I wired it all up, rcas, remote, power wire, ground and wired them up to subs etc. Everything looks good. I turn it on and the amp turns on but it seems as the subs are getting maybe 100 watts they are moving like crazy like they would if they were bumping hard but very little noise is coming out.

I have them in a smaller sealed box.

A couple of problems I could think of:

I have a 250 amp fuse connection the 1/0 gauge to the battery, maybe too much?

Also the box is all good except when the screws screw in the dont stop turning except for 2 screws on each sub all other screws are in there but keep turning when you screw them in. The subs dont rattle or anything so this does not seem like the main problem, eventually I will build myself a nice box.

Any help tips thoughts can help i dont want to take it somewhere if I forgot to mention anything etc please let me know I need your guys help!! thanks

you sure you wired the subs to the correct ohm load?

After checking speaker ohms, check that positive and negative to the amp are right too, out of phase speakers will cancel eachother out.

When you go to put your subs back in, put toothpicks in the screw holes so you can tighten all of the screws.

Running a fuse larger than what's recommended for the gauge of wire you're using it on is a fire hazard. 250 is fine for 1/0 though. If you have a smaller wire off a distrobution block you need to fuse it with the proper fuse (on and within a few inches of) the new, smaller size wire. Finally, if all fuses before your amp are larger than the fuse recommended for your amp then you need to use that smaller size fuse to protect your amp from frying from over current. However, for your particular problem, a 250amp fuse is not causing your problem.

Make sure the gain is set correctly on your amp, read the gain setting tutorial. What HU you using? I have the Alpine 9883. I had to up the subwoofer level on the HU to +15 to make it put out enough voltage for my zx1500.1 to be able to match the level ~75% gain at the max volume I run the HU at (20 out of 40+ max).

Make sure you have a good ground

Check the DC voltage at the amp while you're pounding, if it's dropping below 12v then check your ground again and try the big3.

Anyhow, it may just come down to a shitty box, it can make the most expensive equipment perform like ***.

okay thank you for your help, I have an alpine 9856 and I am in a 2003 ford explorer. The wiring as far as ohms might be wrong is there anywhere I can go website etc to fine the ohm wiring guide or somthing similar. The box isn't bad just somewhat small does the toothpick thing actually work? Any more idea opinions etc would help thanks!!

http://www.crutchfield.com/learningcenter/car/subwoofers_wiring.html?imageID=2DVC%5F2%2Dohm%5FmonoThat is most likely how you will want them wired to get the most out of that amp!

Yes toothpicks will help.

Look on page 2 for wiring diagram: http://www.kicker.com/06/tech-support/manuals/manuals/2006/2006%20CVX%20Sub%20a01%20WEB.pdf

If each coil is 2 ohm, then wire each sub in series which will make each sub 4ohm, then connect both subs to the amp. That will make the amp see a 2ohm load. You should be using 12g or 14g wire.

Awesome guys thanks for the help I don't have the manual so this helps alot I'll try these things then I get home and let you all know!!

Okay I re-wired them the first guy who did it was an idiot, okay a few questions, I am not sure if these subs are 2 ohm or 4 ohm. Now on the bottom of the subs by the magnet it says voice coil 1 + and - and voice coild 2 + and - now for each voice could it have a 2(ohm symbol) does this mean that each voice coil is 2 ohm therfore the subs are 4 ohm each? the guy said they were 4 ohm but he doesnt know s***. Also I dont think my ground is very good because when i turned them on they played for second and then cut out and 3 secs later they played then cut out etc. The light on my zx1000.1 was green then red then green. Could this be because I wired them to a 1 ohm load(which would have happened if these subs are 2 ohm) because i wired them parallel or could this be because my ground is not so good. If this makes any sense at all please help!!!! thanks!!!

Yes they are dual 2ohm VC subs. The amp was seeing .5ohms and was going into protection mode because of this. Wire the coils as series so that each sub ends up with a final 4 ohm load and them hook both subs up directly to the amp and it will see a 2ohm load.

Yep thats what I did now its bumpin! thanks for all the help guys these are awesome thanks agian

wait what???

so if i get 2 subs that are both DVC 2 ohm, can i still wire them to run at 2 ohms?

like if it was a kicker 850.2(425rms at 2 ohms) and powering kicker comps(rated 400rms) i could get them to run at 2ohms also?

whatever you said there just confused everything i know

You can pretty much wire them to whichever ohms you would like!

He has a mono amp, you don't...

One DVC 2Ohm sub can be wired as: 1ohm in parallel or 4Ohm in series.

Now if you parallel both of those at the amp it's becomes .5 ohm if both wired parallel or 2Ohm if both wired in series.

You could also run both in series and series the speakers together to make an 8Ohm load for a home theater, although you'd want to use low watt subs cause HT's don't put out that much power and you want to run near their rated RMS. You don't want to use two 1000 watt subs on a HT that pushes 133 watts.

Since you have a 2 channel amp that puts out it's rated RMS at 2ch @ 2Ohm or 1ch @ 4 Ohm, you would not want two DVC 2Ohm speakers. You would either want to run one DVC 20hm in series or a pair of DVC 4Ohm speakers in series or a different amp.
